Two Carnot heat engines (E1 and E2) are operating in series as shown in figure. Engine E1 receives heat from a reservoir at ๐๐ป = 1600 K and does work W1. Engine E2 receives heat from an intermediate reservoir at T, does work W2 and rejects the rest to a reservoir at ๐๐ฟ = 400 K. Both the engines have identical thermal efficiencies. The temperature T (in K) of the intermediate reservoir is __________ (answer in integer). T = ? TH TL W1 W2 E1 E2
Answer: 800
